An axial magnetic field applied to vertical-cavity surface
emitting lasers induces emission of elliptically polarized
states. The characteristic switching between orthogonal
linearly polarized states with no magnetic field becomes a
switching between elliptically polarized states with low
ellipticity for weak magnetic fields. Stronger magnetic fields
induce time-dependent solutions with two main peaks in the
optical spectrum, with orthogonal elliptically polarized basis
states. Strong magnetic fields induce rotating linearly polarized
emission.
